DETAILED DESCRIPTION

[0017] See also Figures 1 to 4 In an embodiment of the utility model, a material handling device for tunnel construction includes two symmetrically arranged fixed frames 1, one side of one of the fixed frames 1 is provided with a first motor 2, and a limiting rod 5 is fixed at the upper and lower positions between the two fixed frames 1, one end of the first motor 2 is connected to a threaded rod 3, the surface of the threaded rod 3 is sleeved with a connecting sleeve 4, and the interior of the connecting sleeve 4 is provided with an internal thread, and the direction of the internal thread is opposite to the direction of the thread on the surface of the threaded rod 3. Under the rotation of the threaded rod 3, since the sliding sleeve 6 is sleeved on the surface of the limiting rod 5, the connecting sleeve 4 is limited and stabilized, and the connecting sleeve 4 can be moved on the surface of the threaded rod 3;

[0018] The surface of the limiting rod 5 is sleeved with a sliding sleeve 6, the inner diameter of the sliding sleeve 6 is adapted to the diameter of the limiting rod 5, and the sliding sleeve 6 and the limiting rod 5 are both components of a metal material. The sliding sleeve 6 slides on the surface of the limiting rod 5 to limit and stabilize the connecting sleeve 4;

[0019] The sliding sleeve 6 and the connecting sleeve 4 are fixedly connected by a first connecting rod 7, a fixing plate 8 is fixed under one of the sliding sleeves 6, a second motor 9 is arranged on one side of the fixing plate 8, one end of the second motor 9 is connected to a wire wheel 10, a sling 11 is connected to the middle of the wire wheel 10, a transport box 12 is fixed to the lower end of the sling 11, a movable plate 13 is arranged on the front side of the transport box 12, and the transport box 12 and the movable plate 13 are rotatably connected by a hinge 14, and a quick fixing mechanism is arranged between the transport box 12 and the movable plate 13.

[0020] The quick fixing mechanism includes a connecting piece 15 fixed at both ends of the movable plate 13 and a connecting column 16 arranged on both sides of the transport box 12. The connecting column 16 is fixedly connected to the transport box 12 by a fixing piece 17, and a fixing rod 18 is fixed inside the connecting column 16 at one side. A second connecting rod 19 is arranged between the connecting column 16 and the connecting piece 15. A knob 20 is fixed at one end of the second connecting rod 19, and a first longitudinal groove 21 is opened on the surface of the second connecting rod 19 near the other end. A damping sleeve 24 is arranged in the middle of the connecting piece 15, and the damping sleeve 24 is a rubber component. The function of the damping sleeve 24 is to prevent the second connecting rod 19 from moving when there is no external force, so that the fixing effect of the second connecting rod 19 on the movable plate 13 is more reliable. The inner diameters of the first longitudinal groove 21, the transverse groove 22, and the second longitudinal groove 23 are all adapted to the outer diameter of the fixing rod 18. The size of the second connecting rod 19 is adapted to the size of the connecting column 16. When the second connecting rod 19 is pushed, pulled, or rotated, the fixing rod 18 can slide inside the first longitudinal groove 21, the transverse groove 22, and the second longitudinal groove 23, thereby achieving the fixing and separation between the second connecting rod 19 and the connecting column 16.

[0021] A transverse groove 22 is provided on the surface of the second connecting rod 19 at one end of the first longitudinal groove 21, and a second longitudinal groove 23 is provided on the surface of the second connecting rod 19 at one end of the transverse groove 22. When the transport box 12 touches the ground, the knob 20 can be held to pull the second connecting rod 19 toward the outside of the connecting column 16. At this time, the fixing rod 18 slides inside the second longitudinal groove 23. When the fixing rod 18 is located at the intersection of the second longitudinal groove 23 and the transverse groove 22, the second connecting rod 19 is rotated to allow the fixing rod 18 to slide inside the transverse groove 22. When the fixing rod 18 is located at the intersection of the transverse groove 22 and the first longitudinal groove 21, the second connecting rod 19 is pulled toward the outside of the connecting column 16 until the first longitudinal groove 21 is completely aligned with the fixing rod 18. The disengagement of rod 18 means that the second connecting rod 19 is completely pulled out from the inside of the connecting column 16 (the function of the damping sleeve 24 is to prevent the second connecting rod 19 from moving in the absence of external force, so that its fixing effect on the movable plate 13 is more reliable). According to this method, the two second connecting rods 19 are pulled out from the inside of the connecting column 16. At this time, under the action of the hinge 14, the movable plate 13 can be turned down to lower the height of one side of the transport box 12 to facilitate the loading of materials. After loading, first push the second connecting rod 19 into the inside of the connecting column 16, then rotate the connecting rod 19, and finally push it into the inside of the connecting column 16 to fix the connecting column 16 (the principle is the same as above and will not be repeated), and then fix the movable plate 13.

[0022] The working principle of the utility model is as follows: when the transport box 12 is idle at first, it is located above the inside of the tunnel. When it is needed, the second motor 9 needs to be started. Under the positive rotation of the wire wheel 10, the transport box 12 can be slowly lowered. When the transport box 12 touches the ground, the knob 20 can be held to pull the second connecting rod 19 toward the outside of the connecting column 16. At this time, the fixing rod 18 slides inside the second longitudinal groove 23. When the fixing rod 18 is located at the intersection of the second longitudinal groove 23 and the transverse groove 22, the second connecting rod 19 is rotated. The connecting rod 19 allows the fixing rod 18 to slide inside the transverse groove 22. When the fixing rod 18 is located at the intersection of the transverse groove 22 and the first longitudinal groove 21, the second connecting rod 19 is pulled toward the outside of the connecting column 16 until the first longitudinal groove 21 is completely separated from the fixing rod 18, which means that the second connecting rod 19 is completely pulled out from the inside of the connecting column 16 (the function of the damping sleeve 24 is to prevent the second connecting rod 19 from moving when there is no external force, so that its fixing effect on the movable plate 13 is The effect is more reliable), according to this method, the two second connecting rods 19 are pulled out from the inside of the connecting column 16. At this time, under the action of the hinge 14, the movable plate 13 can be turned down to lower the height of one side of the transport box 12, which is convenient for the loading of materials. After loading, the second connecting rod 19 is first pushed into the inside of the connecting column 16, and then the second connecting rod 19 is rotated, and finally it is pushed into the inside of the connecting column 16, so that the connecting column 16 can be fixed (the principle is the same as above, and no more details are given), and then the movable plate 13 is fixed. Subsequently, the second motor 9 is started to pull the transport box 12 upward. After rising to a certain height, the second motor 9 is turned off, and the first motor 2 is started to make the threaded rod 3 start to rotate. Under the rotation of the threaded rod 3, since the sliding sleeve 6 is sleeved on the surface of the limiting rod 5, the connecting sleeve 4 is limited and stabilized, and the connecting sleeve 4 can be moved on the surface of the threaded rod 3, so that the transport box 12 completes the material handling work. Since the transport box 12 is at a certain height, it can effectively avoid obstacles and make the handling efficiency higher.
